What about those serrated heads that help prevent a passthrough or the shaft spring collar things? I'd think the ideal would be to break the back.
Those heads are designed to help compound shooters keep from getting pass-throughs on turkeys. With primitive or even traditional gear I don't think that'll be an issue unless you draw heavy weight. I shot one at 15 yards with a 50# bear recurve sporting a 4-blade Zwickey. I got about 6" of penetration, broke one thigh bone. Shoot your deer broadhead setup at turkeys and you'll be fine.
